SPEQIFICATION forming part of Letters Patent No. 744,774, dated November24, 1903.

Application filed August 18| 190B. Serial No. 169,896. (No model.)

To all whom it may concern.-

Be it known that I, HENRY H. LYON, a citi- I zen of the United States,residing at Riverside, in the county of Riverside and State ofCalifornia, have invented certain new and useful Improvements in RotaryVegetable- Graters; and I do declare the following to be a full, clear,and exact description of the invention, such asl will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the ac` during the grating of the fruit, therebythoroughly grating the fruit, and by the combined influence of the twomovementsa new surface of the fruit is continuously presented to theaction of the cutting or grating surface upon one of the cylinders untilthe fruit is finally discharged` at the ends of the cylin-l ders.

The invention consists, further, in various details of construction andcombinations and arrangements of parts, which will be hereinafter fullydescribed and then specifically defined in'the appended claims.

My invention is illustrated in the accom panying drawings, which", withthe letters of reference marked thereon, form a part of thisapplication, and in which drawings similar letters of reference indicatelike parts throughout the various views, in which- Figure lis an endView showing my iinproved rotary grating apparatus. Fig.- 2 is a topplan view. Fig. 3 is an enlarged detail View of the surface of one ofthe cylinders. Fig. 4 is an enlarged sectional View showing agratingsurface ono`ne cylinder. Fig. 5 is an enlarged detail view of thesurface of the other cylinder, and Fig. 6 is a sectional view throughFig. 5.

Reference now being had to the details of the drawings by letter, Adesignates a box or receptacle fromwhich rise standards B, in

.which the two cylinders C and D are mounted in suitable bearings, theformer of which cylinders C has a circumference having perforations Ctherein, which have outwardlyextending burs C2 about their margins, asshown clearly in the sectional View, Fig. 4. Mounted upon the shaft E,which carries cylinder C, is a pulley E', which has belted connectionwith a pulley F, mounted upon the shaft F', on which the cylinder D ismounted. Said pulley F is' of larger diameter than the pulley E, and abelt G passes about said pulleys and is adapted to impart an acceleratedrotary movement to the cylinder O as the two rotate together. Thecircumference of the cylinder D has a series of elongated slots KthereinLshown clearly in the detail face of the cylinder C.

In operation the fruit (indicated by the dotted line Q in Fig. l of thedrawings) is placed between and resting upon the surfaces of the twocylinders. As the pulleys E and E are of different sizes,the speed ofthe two cylinders will be inversely proportionate to the diameters ofsaid pulleys, and the fruit will be acted upon by the grating-surface ofthe cylinder C, which has the higher speed, but is prevented by theprojections or burs K' on the other cylinder from turning faster thanthe circumferential speed of the cylinder D. Consequently a rotativemovement in the direction of the arrow, as shown in Fig. 1 ofthe'vdrawings, is given the fruit, and owing to the greater speed of thecutting-surface onl the circumference of the cylinder C a narrow bandaround the surface of the fruit is grated off and falls into thecylinder C through theperforations C', and by the action of the spiralM, carried by the cylinder D, an additional rotative movement isimparted to the fruit roc Y which is at right angles to the planeof therotative movement described, so that under the combined inii uence ofthe two movements a new surface of the fruit is continuously presentedto the action of the grating-surface on the circumference of thecylinder C until it is inally discharged at the ends of the cylinders.

While I have shown a particular construction of apparatus embodying myfruit-grater, it will be understood that I may make alterations in thedetailed construction of the same without departing from the spirit ofthe in vention.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. A rotary fruit-grating apparatus cornprising a receptacle, twocylinders mounted therein and mechanism for driving the same atdifferent speeds, the surface of one cylinder having perforations, theupper marginal edges of which are outwardly turned to form a cutting orgrating surface, the other cylinder provided with elongated slots in itscircumference with outwardly-extending burs Vadapted to hold the fruitto rotate at the same rate of speed as the cylinder having the elongatedslots to be acted upon by the gratingsurface on the circumference of theother cylinder, and means for moving the fruit 1ongitudinally along thecylinders, as set forth.

2. A grating apparatus comprising two rotary cylinders adjacent to' eachother and means for driving the same at different speeds, thecircumferences of said cylinders being perforated, portions of thecylinders adjacent to said apertures being formed into burs to produce agrating-surface, and a spiral wing on the circumference of one of thecylinders for feeding the fruit along the cylinders as the fruit isbeing grated, as set forth.

3. A rotary grating apparatus comprising two cylinders, and means fordriving the same at dierent speeds, the circumference of thefaster-rotating cylinder having apertures portions of the marginal edgesof which are outwardly turned to form burs, the other slowermovingcylinder having acircumference with elongated slots, portions of themarginal edges of which are formed into burs, a spiral feeding-wingmounted upon the circumference of the cylinder which rotates at a slowerspeed, the burs about the marginal apertures of the elongated slotsdesigned to engage fruit and cause the same to turn at the same rate ofspeed as the cylinder having said elongated slots, whereby a continuousband is grated about the fruit by the rapidly-rotating cylinder as thefruit is advanced by the spiral feed, as set forth.

4. A grating apparatus comprising two rotary cylinders and means fordriving the same, adapted to be rotated at different rates of speed, thecylinder having the higher speed being provided with a cutting orgrating surface, the cylinder with the lower speed being provided withprojections or burs adapted to engage the fruit and prevent it fromturning faster than its own circumferential speed, a spiral feed-wing,mounted upon the circumference of the cylinder having the lower speed,and adapted to impart a motion to the fruit at right angles to themotion imparted by the cylinders, whereby under the influence of the twomotions, a surface of the fruit is continuously presented to the gratingaction of the cylinder having the higher speed, as set forth. Intestimony whereof I hereunto aliix my signature in presence of twowitnesses.
